Thanks for the logs, UUIC they are from a successful run. I have reproduced an equivalent hugepage layout and mempool spread between hugepages, but I don't see the error behavior in several tries. What are the logs in case of error? Please note that the offending commit you found (fec28ca0e3a9) indeed introduced a few issues, but they were fixed later, so I'm testing with 21.11, not that commit. Unfortunately, none of those issues resembled yours.
